| Plan B & Grease Monkey,
Thank you for replying back to my post. U boy's sure had me confuse their for a while with compression ratio ect ect.....
I don't have much experience with turbo's on cars yet but I don't have lots of experience (10 years) with 2 stroke snowmobile engines. I know for a fact, the leaner you make it, the more POWER you make. Yes, their is that fine line you can't cross but if you can get close to that fine line without melting the piston you can make a lot more power. By leanning out the fuel management on a snowmobile, your not only making more power but your also saving on fuel consumption and less BLACK SMOKE coming out of the exhaust. Also, a good way to check for a clean burn on a snowmobile is looking at the "burnt line" on a spark plug. If you know how to read a spark plug from a "clean lean burn" to a "rich fat burn" you will know for sure what's the next step to do.
Plan B,
The only thing that I did to the car so far is added the Blow Off Plate from ModernPerformance. I can't see how that could change the performance of the car. I mean, I would think it would help it because your dumping that HOT air into the atmosphere RIGHT? Asside from that, I did nothing else to it. I plan on putting the K/N Air filter from ModernPerformance on the car soon, but I want to make sure I don't do any damage to the turbo what-so-ever. I also do not want to void the warranty either.
Correct me if I'm wrong, but if you richen the fuel management system on a car that has O2 sensors, the O2 will tell the ECU to lean it out, but if the ECU has it's own parameters, then that means it can only lean it so much.... RIGHT?
One thing I also want to mention to both of you is that on certain day's on my commute to and from work the boost pressure varies depending on coolant temps. When the engine is around the 140 - 160' it wil only make 5psi according to the boost gauge. When coolant temp reaches 180 - 190' then it fluctuate between 10 - 15 psi. At times it will go to 15psi but then drops to 10psi and stays right there ti'll I let off the throttle. Is that right??
Thanks again guy's, I really appreciate all your help and looking forward to some of your feedback.
